As JAX-RS requires use of annotations, you will need to create part of
the code in plain Java. After that you can use standard gen-class/
proxy macros for the rest of your application.

Macro will not work in this situation, but you can write it as:

what amounts to a distributed repository.
There is no centralized repository with Ivy. You can build one, but
with Packager resolver every project can create its own repository, it
can even keep it in /repo dir in its git/hg/svn tree.

Sorry about that, didn't see that :b should concat it's vals:
(def x [[:a 1] [:b 3] [:b 5] [:c 1]])
(reduce (fn [x [k v]] (assoc x k (if (contains? x k) (conj (x k) v)
[v]))) {} x)
Returns:
{:c [1], :b [3 5], :a [1]}

m one task/target script with others.
If you can't solve this with normal Ant construct you can drop down to
Java and create new Task, or even in Clojure (you will need to
initialize your antlib with classpath set to point to clojure.jar).

library, it is easy to use it
even if jar is not in external repository, url resolver can just
download it from web, or packager resolver can extract jars from other
archive types like zip files located on external server, custom
resolver are also supported.

Or you can use gen-class instead of gen-interface and implement Foo as
concrete class. Proxy will accept any method name you give him, but it
will expose only methods in class and interfaces it extends.

Hi,
(rand-int 49) will produce one integer, and repeat will repeat it 10
times, that is why you see same number repeated.
To fix this use:
user=> (take 10 (repeatedly #(rand-int 49)))

If you want offline version of clojure.org:
hg clone https://bitbucket.org/ksojat/truba/
cd truba
ant clojure-org-download
(requires wget)
When finished, it will place it in dist/clojure.org directory.
Or you can just copy wget command from clojure-org-download target.
